Merge tag 'fixes-v4.0-rc4' of git://git.kernel.org/pub/scm/linux/kernel/git/tmlind/linux-omap into fixes

Fixes for omaps for the -rc cycle:

- Fix a device tree based booting vs legacy booting regression for
  omap3 crypto hardware by adding the missing DMA channels.

- Fix /sys/bus/soc/devices/soc0/family for am33xx devices.

- Fix two timer issues that can cause hangs if the timer related
  hwmod data is missing like it often initially is for new SoCs.

- Remove pcie hwmods entry from dts as that causes runtime PM to
  fail for the PHYs.

- A paper bag type dts configuration fix for dm816x GPIO
  interrupts that I just noticed. This is most of the changes
  diffstat wise, but as it's a basic feature for connecting
  devices and things work otherwise, it should be fixed.

The UART reference clock speed is 7273.8 kHz, not 72738 kHz.

Dots aren't usually used in node names even though ePAPR permits
them.  However, this can easily be avoided by expressing the
frequency in Hz, not kHz.

This patch changes the name to refclk7273800hz, reflecting the
actual clock speed.

The socfpga.dtsi currently has the wrong interrupt number set for SPI master 1
Trying to use the master without this change results in the kernel boot
process waiting forever for an interrupt that will never occur while
attempting to probe any slave devices configured in the device tree as being
under SPI master 1.

The change works for the Cyclone V, and according to the Arria 5 handbook
should be good there too.

Commit 7800064b ("ARM: dts: Add basic dm816x device tree
configuration") added basic devices for dm816x, but I was not able
to test the GPIO interrupts earlier until I found some suitable pins
to test with. We can mux the MMC card detect and write protect pins
from SD_SDCD and SD_SDWP mode to use a normal GPIO interrupts that
are also suitable for the MMC subsystem.

This turned out several issues that need to be fixed:

- I set the GPIO type wrong to be compatible with omap3 instead
  of omap4. The GPIO controller on dm816x has EOI interrupt
  register like omap4 and am335x.

- I got the GPIO interrupt numbers wrong as each bank has two
  and we only use one. They need to be set up the same way as
  on am335x.

- The gpio banks are missing interrupt controller related
  properties.

With these changes the GPIO interrupts can be used with the
MMC card detect pin, so let's wire that up. Let's also mux all
the MMC lines for completeness while at it.

For the first GPIO bank I tested using GPMC lines temporarily
muxed to GPIOs on the dip switch 10.

The current OMAP dmtimer probe does not check for the return
status of pm_runtime_get_sync() before initializing the timer
registers. Any timer with missing hwmod data would return a
failure here, and the access of registers without enabling the
clocks for the timer would trigger a l3_noc interrupt and a
kernel boot hang. Add proper checking so that the probe would
return a failure graciously without hanging the kernel boot.

The ARM architecture allows the caching of intermediate page table
levels and page table freeing requires a sequence like:

	pmd_clear()
	TLB invalidation
	pte page freeing

With commit 5e5f6dc1 (arm64: mm: enable HAVE_RCU_TABLE_FREE logic),
the page table freeing batching was moved from tlb_remove_page() to
tlb_remove_table(). The former takes care of TLB invalidation as this is
also shared with pte clearing and page cache page freeing. The latter,
however, does not invalidate the TLBs for intermediate page table levels
as it probably relies on the architecture code to do it if required.
When the mm->mm_users < 2, tlb_remove_table() does not do any batching
and page table pages are freed before tlb_finish_mmu() which performs
the actual TLB invalidation.

This patch introduces __tlb_flush_pgtable() for arm64 and calls it from
the {pte,pmd,pud}_free_tlb() directly without relying on deferred page
table freeing.

The current HDA generic parser initializes / modifies the amp values
always in stereo, but this seems causing the problem on ALC3229 codec
that has a few mono channel widgets: namely, these mono widgets react
to actions for both channels equally.

In the driver code, we do care the mono channel and create a control
only for the left channel (as defined in HD-audio spec) for such a
node.  When the control is updated, only the left channel value is
changed.  However, in the resume, the right channel value is also
restored from the initial value we took as stereo, and this overwrites
the left channel value.  This ends up being the silent output as the
right channel has been never touched and remains muted.

This patch covers the places where unconditional stereo amp accesses
are done and converts to the conditional accesses.
